ARCTIC P14 PWM PST case fans, 4-pin, 140mm, black, 5 pcs.

Case fans P14 PWM PST, 4-pin, 140mm, black, x5 pcs. Features: PWM PSTtechnology allows you to connect multiple fans (up to 5 recommended), synchronizing their operating speed based on the actual cooling needs of the computer. This way, the entire cooling system operates more efficiently and quietly, and the overall energy consumption is lower than when connecting each fan/cooler separately. Optimized for static pressureWhen developing the new P14 PWM PST fan, special attention was paid to focused airflow and static pressure. This fan guarantees extremely efficient cooling, even with increased air resistance. Maximum silence, minimum vibrationEven at low speeds, the operating sound of the new ARCTIC motor is barely noticeable. Thanks to the sinusoidal magnetization, the new motor is very smooth and almost vibration-free - it produces only about 5% of the vibration level of a conventional DC motor without a filter. As a result, the fans do not need to use anti-vibration pads. More efficient technologyThe motor is powered by a next-generation PWM integrated circuit, enabling the new P14 PWM PST to operate more efficiently than previous models. It saves energy and reduces coil temperatures without compromising performance. High quality bearing. The German-developed alloy and grease combination reduces friction in the bearing and provides greater efficiency. This results in less heat and noise from the bearing, so you can enjoy a longer lifespan for your fan. 200-1700 rpm speed, PWM adjustable. Thanks to the 4 pins, the speed can be adjusted over a wide range via PWM (pulse width modulation), i.e. the fan changes the speed/airflow as needed, depending on the temperature. In addition, thanks to the PWM sharing technology (PST), the speed of this fan can be controlled synchronously with all other fans together. This way, noise is minimized and maximum cooling efficiency is ensured when needed. Long service life. 10°C lower motor temperature approximately doubles the fan life. The new ARCTIC motor has a significantly longer life due to the low coil temperature. Therefore, the warranty has been extended to 6 years. Two modes of operation.
